HOSE COUPLING.

.Applicationf filed December 17,1923.

To aZLw/wcmmay concern: g

fBe itlknown that` I, Osvvnnn H. HANSEN, a vcitizengfof `Norway,:residing at NeW York Kings v. and State. of:.NeW .York, have .1inuented certain new ,and aisefullmprovementsfin Hose Couplings, yof `.vhich ithe `following `is a specification.

This invention relates tosmprovementsin hose fcouplings, and {isgidesignedgmore paritoularly for use on the outlet tube or hose otanjairpump 4-foruiluiclr and effectual coupling with the valve containing tire nipple of auto-mobiles and the like.

An object of the invention is to provide a coupling of this character which grips the threads of the nipple by the compressionof au elasticring and the operation of the latter to grip and release is due to the longitudinal movement of theV outer shell of the coupling.

A further object is to provide a coupling of the character stated which is capable of `a Wide utility as a coupling means for various uses, and which: is of extreme simplicity of construction and design, and which can he manufactured and sold at an extremely low price.

llVith these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as Will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings Figure 1 is a fragmentary view in side elevation of my improved coup-ling with a portion of the outer shell broken away.

Figure 2 is a view in longitudinal. section through the center of Figure 1.

Figure 3 is a view similar to Figure 1 but of the opposite side of the coupling.

Figure 4 is a view in elevation on a reduced scale of the complete coupling sho\v ing by dot and dash i'lines the extreme movement of the shell.

Figure 5 is a bottom coupling.

Figure 6 is a View in transverse section on the staggered line 6-6 of Figure 2.

Figure 7 is an inverted plan view showing the fixed and movable rings in their proper normal relation to each other.

1 represents the outer shell and 2 the inner cu member of my improved coupling. he shell is in the form ofa sleeve plan vieuT of theA rSerial No. 681.078.

littingthe cup .but movable thereon, and

preferably lmilled or otherwise :roughened on its outer face.

A :nipple 3 is :secured `in .thevclosed end. of the cup i-nany approved mannerand cai ries affixed plunger V11i: atits inner end to engage a. valve stem (not shown) to `open thevalve of ya ftire nipple or fother device on avhiclrthecoupling is to be positioned.

iThe` curp l2-encloses afl'uhber or other elastic gripping ring 4:, witha .Washer 5 at' the outer endfofzrthe ring, and a=cam ring 6 is located against the Washer 5 and has a lug 7 thereon projecting through an opening 8 in the'vvall of the cup 2.

A fixed cam ring 9 is secured in the end of cup 2 and is made with radial segments 10 fitting corresponding recesses 11 in the end of the cup and held in place preferably by upsetting portions of the end of the shell to form securing lugs 12 as shown most clearly in Figure 5.

The rings 6 and 9 are made With any desired number of cooperating cam faces 13 so that when the ring 6 is turned in one direction it will be moved inwardly to compress the elastic ring 4; and grip a nipple, and when the ring 6 is turned in the opposite direction, it Will permit the ring 4- to expand and release the nipple.

To cause this turning action of the ring 6, the shell 1 is made vwith an inwardly projecting key 15 which rides in an inclosed or diagonal lreyway 16 in the outer face of cup 2 thus compelling turning movement of either part. The shell, however, is formed in its inner face with a longitudinally eX- tending straight groove 17 to receive the lug 7, so that when the cup 2 and shell 1 are moved longitudinally in opposite directions, by pressure on a hose nipple for example, a turning movement will be imparted to the ring 6 to compress the elastic ring 4: or permit expansion thereof as the case may be.

It Will thus be seen that the operation` of coupling is due to a pressure on the shell 1 after the cup 2 is on the nipple, and the release is effected by a pull on the shell. Both movements cause a turning action of ring 6 which due to the cam faces 13 causes or permits a longitudinal movement of the ring 6 in cup 2.

Various slio'ht changes might be made in the general form and arrangement of the parts described Without departing from the spirit or scope of the appended claims.

l claim:

l. A coupling, comprising a cup, a shell movable longitudinally on the cup, an elastic ring in the cup, a fixed ring at the end of the cup, a compressing ring in the cup having cam engagement with the fixed ring to cause the same to move longitudinally in the cup When turned, and means on the compressing ring engaging the shell whereby a rotary movement is imparted to the compressing ring when the shell and cup are moved longitudinally in opposite directions.

2. A coupling comprising a cup, a longitudinally movableshell on the cup, a fixed cam ring in the end of' the cup, a movable cam ring in the cup engaging the fixed cam ring, and caused to move by the relative longitudinal movements of the cup and shell, and an elastic ring in the cup engaged by the movable cam ring.

A coupling, comprising acup having ssgcam faces at its open end, an elastic ring in the cup, a movable cam ring engaging the elastic ring and also the fixed cam faces of thc cup, a lug` on the movable ring, and said .i

shell having a groove therein receiving the lug and compelling a movement of said ring when the shell and cup are moved longitudinally relative to each other.

4. A coupling, comprising a cup, a longitudinally movable shell on the cup, a key on one of said parts and the other of said parts having an inclined lzeyivay receiving the key, a longitudinally movable member in the cup caused to move longitudinally When turned,
